Are you preparing us for your own post or just insulting everyone here
on general principles?

The point, yet again, is that according to general relativity, the sun
CAN'T just "disappear," since this would violate (local) conservation of
energy.  So GR makes no predictions about what would happen in this
Of course, this experiment has not been done.  However, there seems to
be pretty good evidence from the double neutron star observations that
GR does well at predicting how gravitational radiation works.
